/*
* This example is used to generate the file:
*
*
* There is a flaw in the DICOM design were it is assumed that Sequence can be
* either represented as undefined length or defined length. This should work
* in most case, but the undefined length is a little more general and can
* store sequence of items that a defined length cannot.
* We need to make sure that we can store numerous Item in a SQ
*
* Warning: do not try to compute the group length elements !
* Warning: You may need a 64bits machine for this example to work.
